Integer32
This value determines the initial contention resolution back-off window used by the SU when attempting to transmit data packets. The SU randomly selects a number within the back-off window defined by this parameter then defers this number of contention transmit opportunities before actually attempting the transmission. Expressed as a power of 2. A value of 16 at the HE indicates that a proprietary adaptive retry mechanism is to be used.
